2. true or false, explain why the state is false : Bipolar neurons have a central cell body with two extensions: true

  1. List the phases of an action potential in order: 1. resting potential
  2. depolarization 3.repolarizarion 4.resting condition
  3. true or false , if false explain why the statement is false: the central nervoussystem consists of the brain and spinal cord: true
    1. the neuron pictured below, is best described as: multipolar

2 / 6

  1. name and describe what is occurring in the neurocell membrane in section2 of the diagram. include the charge of the membrane during this phase: de- privation, sodium gates are opened and the sodium floods into the axon admits thedepolarization of the action potential, causing the charge voltage to go from 0 to +40mV 6. This part of a reflex is inside the CNS, made up of one or more synapses.: - integration center
  2. match the following lobes of the brain with the correct function: temporal - contains sensory areas for hearing and smelling frontal- contain higher levels ex.. pariteal - receives sensory info from body receptorsoccipital - interprets visual input
  3. which of the following structures of the spinal cord contains the cell bodiesof afferent neurons: dorsal root ganglion

4 / 6

  1. which of the following is most likely a symptom of ASL: impaired ability toswallow
  2. describe the function of the parasympathetic nervous system: aka the housekeeper system because it promotes all of the internal responses in the relaxedstate. Parasympathetic stimulation causes the pupil of the eye to get smaller and aids the lenses of the eyes to focus on close items. it helps with the digestion of foodand also helps with the beating of the heart and slowing it
  3. which of the following visual conditions is caused by damage to theabducens nerve?: diplopia
  4. what is the purpose of the blood brain barrier? describe its maintenance from a cellular level: it is a diffusion barrier that helps in the prevention of unneededmaterials that attack the CNS by keeping the brain and spinal cord away from the general blood bank.It is composed of the gilal cells astrocytes and its pertinent for regulation to be able to keep a homestatis which aids in protecting the neurons

5 / 6

  1. a pt is unable to extend his left wrist or fingers. what never is most likelydamaged ?: radial nerve
  2. explain the main steps in the process of hearing: 1 .) sound waves are funneled through the external auditory Canal which causes the eardrum to vibrate
  3. the vibrations go into the ossicles and push against the fluids inside the cochlear duct. the movement of the fluid causes the stereocilla in the organ of court to move as well.the neurons are stimulated to send impulses through the cochlear nerve tothe primary auditory cortex of the temp lobe
  4. which cell serves as stem cells in the gustatory system that divide and differentiate into new supporting cells then form new gustatory cells: basalcells
  5. fill in the blanks: the two upper receiving chambers of the heartier called the , while the two lower pumping chambers are called the: ratio , ventricles

7 / 6 ndicated by

  1. a bolus is formed by the : tongue
  2. T/F: The tongue contains nociceptors and thermoreceptors in addition tochemoreceptors.: true
  3. what's the purpose of the fossa avails in a fetus: the fossa marks the placeof opening between the atria which is present in all growing fetuses. it permits bloodto flow directly Erin the right t the left atrium,. the fossa closes during birth so the lungs can gain access to oxygen once the baby is born
  4. Name the vessel in the figure below: (highlighted in blue, also ithe arrow): circumflex branch 3.)cochlea 4.)tympanic membrane 5.)incus

8 / 6 hatic duct

  1. use the figure below to answer the following : which part of the medicalequipment (b-f) is squeezed to inflate A: F. the bulb
  2. oxygenated blood is pumped from the heart through the to the rest of the body .: left, systemic circuit
  3. you are reviewing your pts results from an egg. the findings indicate a problem with ventricular depolarization. where should you look on the keg tofind this abnormal rhythm: qrs complex
  4. a pt is suspected to have peripheral edema due t heart failure. which side of the heart would be in failure? explain: the right side of the heart because right sided heart disease usually causes the backup of fluids in the limbs of the body
  5. name the lymphatic vessel below highlighted in blue: right lymp

10 / 6 gure below- the uterus in the longest lactic shock due to a dramatic decrease in blood pressure and closed respiratorypassageways

  1. match the cell with its best description. select all that apply: has the greatest phagocytosis properties of the white blood cells: macrophage andmonocyte
  2. label the regions of the reproductive system below (a-c): a. prepuce b. urethral orifice c. vestibule
  3. the connects the seminal vesicle with the urethra to allow sperm to exitthe body: ejactulary duct
  4. which of the following is true concerning human cells?: gamete cells arehaploid cells 39. name ad discuss the stage of labor that best describes the fi : the dilation of the cervix, which has to reach 10cm and once it does,contracts and the baby's head is pushed against the cervix

11 / 6 dilating it stage of labor

  1. based strictly on anatomical structural differences, are males or femalesmore likely to get a UTI? why or why not: females because the female urethra is shorter and located near the anus which causes for poornhygienve after bowel movements. not wiping correctly can cause the feca bacteria to inhabit the urethraand trade within the urinary system and cause a UTI
  2. what causes an extremely high blood pressure in the glomeluar capillar- ies: the difference in diameter causes very high bp which results in the water andsolutes to exit the blood and make their a inside of the glomeluar capillaries whichare known to filtrate
  3. which of the following is false concerning the cardiovascular barorecep-tors: if blood volume rises, they cause constriction of the afferent arterioles

13 / 6 indicated by the kidneys to other pertinent organs, when the nervous system takes over controlthe afferent arteriole diameter becomes smaller

  1. list the 4 parts of the human brain: cerebral hemispheres, diencephalon, brainstem, cerebellum
  2. list and describe the 3 meninges of the human brain: 1. the leathery duramater which is composed of the double layered outer meninx
  3. the middle arachnoid meninx which is loose layer separated from dura mater bythe subdural space
  4. the inner Pia meninx is composed of connective tissue and is tightly attached tothe brain
  5. What blood cells contain hemoglobin?: red blood cells
  6. P waves represent what?: atrial depolarization
  7. Define systole: Contraction of the heart
  8. what is muscle tone and how is it maintained: Muscle tone is the degree atwhich muscles remain partially contracted while at rest. Muscle tone is

14 / 6 continuouslymonitored and maintained by the cerebellum to keep bones and joints in place.

  1. Name the vessel in the figure below: (highlighted in blue, alsothe arrow): posterior interventricular artery
  2. a pt is suspected to have peripheral edema due to heart failure. which sideof the heart would be in failure? explain: the right side of the heart be in failure,if the right side of the heart cannot pump blood into the heart efficiently, blood and fluid will back up into the veins, causing swelling in body tissues.
